Service Host Superfetch High CPU usage problem.
Like any other Windows features, Superfetch may also go wrong sometimes and may cause high CPU usage problem. This process always runs in the background thereby using certain amount of both RAM and CPU. If too many apps are open at the same time or your hardware are weak, your PC may slow down considerably and you will experience the Superfetch high CPU usage problem.
Although it is annoying, it is not dangerous. It gradually settles down and automatically adjusts with the running apps and the high disk usage eases. But if the PC is running for quite some time, the host file quickly fills up the RAM and runs out of memory.

If you find yourself in such a situation that service host Superfetch is always causing high disc usage, then you have to disable it.
